处理BigInteger问题

假设以下Diffie-Hellman信息也可以在此页面上找到 1）p string givenp = “00e655cc9e04f3bebae76ecca77143ef5c4451876615a9f8b4f712b8f3bdf47ee7f717c09bb5b2b66450831367d9dcf85f9f0528bcd5318fb1dab2f23ce77c48b6b7381eed13e80a14cca6b30b5e37ffe53db15e2d6b727a2efcee51893678d50e9a89166a359e574c4c3ca5e59fae79924fe6f186b36a2ebde9bf09fe4de50453”; BigInteger p = new BigInteger(HexToBytesv2(givenp)); 2）G BigInteger g = new BigInteger(2); 3）商家私钥 string merchantPrivateKeyHEX = “48887dfd090d175e33beea29e7b38334299289069f9ab492b67807905faa98d96d22d79205bef03f14af093f1797b904734132c34a388fdc79e20497bfa1465fec2aac4fabdf3bb0c9be8685d20f7bfe0346a9abdf7fa89838c3fa9ca6abdb70bea66795ab6699cc154db59490e4159f142f7bddff603c1d3d6c4fff8177e11d”; BigInteger a = new BigInteger(HexToBytesv2(merchantPrivateKeyHEX)); 使用公式publickey = g ^ a mod p我应该获得初始链接中提供的公钥，但是在执行时 BigInteger A = BigInteger.ModPow(g, a, p); ToHex(A.ToByteArray()) 我得到的结果是 00f85c41e84446ecfe43c9911df31d3cf60d83642afd496b741363290139badf75f8b8c5c010dda2446dd483dc553b6c2698c16c9d082391677785f81d54bc9c7c45f8b6d5bdb3e49fec7f5522b880c8c753fb7d3ff2c81e47dcb27d52842def40a812dc95cc679575baf237a955ee9944bd0797326f2a0a58c6c087f9b0b9e82c 代替 00d9abd78c93dfddeb920d57d6513126d8f1118c9237a45101408dbffe6cfd95b011a016e4e0ab8aef0601e836a452b8bb88be7ca71e4f22f97aa65f8358ee69348d1227d65db6e53641d1a6542aa4be4b4adc75fac816af79a8e3f5097f8313e7b725df37eadc8c774e2033dfa99c95ccef333bf402b066198c30481e2a83875c 有任何想法吗？ 我一定很遗憾，但我不确定那可能是什么。 PS添加正在使用的function： public static byte[] HexToBytesv2(this string hex) { […]
